seq2graph: Discovering Dynamic Dependencies from Multivariate Time Series with Multi-level Attention

no code implementations7 Dec 2018 Xuan-Hong Dang, Syed Yousaf Shah, Petros Zerfos

We introduce a key component of Dual-purpose recurrent neural network that decodes information in the temporal domain to discover lagged dependencies within each time series, and encodes them into a set of vectors which, collected from all component time series, form the informative inputs to discover inter-dependencies.
